Residual products of the chemical or allied industries, not elsewhere specified or included; sewage sludge

HS v2022 Code: 382520

About residual products of the chemical or allied industries, not elsewhere specified or included; sewage sludge

HS code 382520 covers a diverse range of residual products from the chemical and allied industries that do not fit into other more specific categories. This includes materials like sewage sludge, which are byproducts of various industrial and municipal processes. While these residual products may not be the primary focus of their respective industries, they play an important role in waste management and the circular economy, finding uses as inputs for other processes or being disposed of responsibly.

Production process

The production techniques for the materials covered under HS code 382520 can vary widely depending on the specific product. Sewage sludge, for example, is generated through the treatment of wastewater in municipal and industrial facilities. It undergoes processes like dewatering, stabilization, and sometimes further treatment before being disposed of or utilized. Other residual products may be separated, filtered, or processed in different ways to prepare them for their intended uses or disposal.

Production inputs

The inputs required for the industries covered by HS code 382520 are largely dependent on the specific residual product. Sewage sludge, for instance, requires wastewater treatment infrastructure, energy, and chemicals for the various processing steps. Other residual products may rely on the outputs of their parent industries, such as chemical manufacturing or industrial processes. Common inputs can include machinery, energy, and labor for handling and preparing the materials.

Production outputs

The outputs of the industries covered by HS code 382520 can be quite diverse. Sewage sludge, after appropriate treatment, may be used as a soil amendment or in the production of 310100 fertilizers. Other residual products could be utilized as feedstock for 382490 other chemical products, 382499 other chemical products and preparations, or even 382490 other chemical products in a circular economy approach. However, some materials may also require responsible disposal through methods like landfilling or incineration.
